Float ceil float x.

Floor int c.

Rounds downs the nearest integer. It takes single value whoes floor value is to be calculated. Returns the largest integer that is smaller than or equal to x i e. Otherwise if arg has integer type or the type double floor is called.

In mathematics and computer science the floor and ceiling functions map a real number to the greatest preceding or the least succeeding integer respectively. The floor function returns the largest integer that is smaller than or equal to x. However the result may overflow any integer type including std intmax t when stored in an integer variable. 1 3 computes the largest integer value not greater than arg.

Floor has an implementation that uses streaming simd extensions 2 sse2. Float floor float x. C allows overloading so you can call overloads of floor that take and return float and long double values. For information and restrictions about using the sse2 implementation see set sse2 enable.

Here x is the floating point value. The floor function returns the largest possible integer value which is equal to the value or smaller than that. Double ceil double x. Round down value rounds x downward returning the largest integral value that is not greater than x.

The largest representable floating point values are exact integers in all standard floating point formats so this function never overflows on its own. Double ceil t x. Double floor double x. Long double floor long double x.

The value to round down to the nearest integer. This function is also declared in cmath header file in c language. Additional overloads for integral types. In the c language the required header for the floor function is.

If arg has type long double floorl is called. Long double ceil long double x.
